Pixel 3 Adaptive Brightness Stopped Working

Recently I noticed the adaptive brightness of my phone doesn’t work. Here is the fix:

1. Open Settings and click Apps and notifications

2. Click on the link See all 123 apps

3. Find an app called Device Health Services and click it

4. Open Storage & cache of the app and click Clear storage

5. Click on the button Reset adaptive brightness

6. It seems to work for the moment
